DUPLEX STOCK-FOUNTAIN.

Specification of Letters Patent.

Patented May 13, 1919.

Application filed May 13, 1918. Serial No. 234,160. I

To all whom it may concern:

- Be it-known that 1, WILLIAM A; McCoL- LOUGH, a citizen of the United States of America, and resident of Webster City, Hamilton county, Iowa, have invented a new and useful Duplex Stocl:-Fountain, of which the following is a specification.

The object of this invention is to provide an improved construction for watering tanks adapted for supplying drinking. water to the largerdomestic animals, such as cattle and horses, and also to smaller animals such as hogs.

A further object of this invention is to provide an improved construction for a dupleX stock fountain involving a relatively large drinking tank and a valve-controlled relatively small drinking tank receivingits supply from the largervtank automatically from time to time as required. 1

A further object of this invention is to provide improved means for automatically replenishing the water supply in a drinking tank mounted on a rocking frame, such means including a valve and operative connections between said frame and valve to open the valve when the frame is in one position and close it when the frame is in another position.

A further object of this invention is to provide an improved governing device carried by the operative connections between the rocking frame and valve and designed to prevent too frequent oscillation of the frame, and consequent operation of the valve.

A further object of this invention is to provide improved means for removably and replaceably mounting the drinking tank on the rocking frame, to facilitate cleaning of the tank or trough.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the [accompanying drawing, in which Figure 1 is a plan of my improved duplex fountain, a, portion being broken away to economize space, the cover of the hog trough compartment being removed. Fig. 2 is a side elevation of the device, a portion being broken away. Fig. 3 is a detail section, on an enlarged scale, on the line 33 of Fig. 1. Fig 4 is a plan, partly in section, of the automatic valve. Fig. 5 is a vertical section on the line 55 of Fig. 4:. Figs. 4 and 5 are on a scale enlarged relative to Figs. ,1

and 2. Fig. 6 is an end elevation of the device. Fig. 7 is a cross-sectionon the indicated line 7-7 of Fig. 1, the hog trough being shown in depressed or lowered position, as when full. Fig. 8 is alongitudinal section on the indicated line 8--8 of Fig. 1, the cover being removed.

In the construction of the device as shown the numeral 10 designates a side wall and 11 a bottom of a tank structure, said members preferably being formed of galvanized sheet metal and secured to angle steel frame members 12 in any suitable manner, as by riveting or soldering,0r both. The side wall 10 may be continuous from end to end and in its central portion curved on the arc .ofa circle, in plan view, to form a rounded end for the tank structure; and at the opposite end of the structure said side wall terminates at the ends of the longer sides of the structure and leaves said opposite end open except as hereinafter set forth. A

partition 13 is mounted transversely across the tank structure near the square or open end portion thereof and is sealed to watertight condition, thus dividing the tank struc ture into a major and a minor portion, the former portion comprising the drinking trough for the larger animals, such as cattle and horses; while the minor portion contains the drinking trough or pan for smaller animals, together with the operating devices connected therewith. The smaller drinking trough is designed to receive its supply of water from the larger trough automatically from time to time as required for use.

A rock shaft 1A is mounted in and near the bottom of the minor compartment and is removably carried for oscillatory movement in bearing members 15, 16, substantially on the median longitudinal line of the tank structure but preferably a little to one sideof said median'line. A rocking frame 17, prefera'bly of angle iron bars suitably and rigidly connected, is mounted on the shaft 14 and is arranged transversely and substantially fills the lower portion of the minor compartment of the structure and is designed for limited oscillatory movement on the axis of said shaft. At one end of the rocking frame 17, and entirely to one side of the 14 thereof, a trough supporting frame 18 is mounted on and rigidly secured to said rocking frame. Slideways 19, 20 are carried by and longitudinally of the trough supporting frame 18, and a drinking trough or pan 21 is provided and is adapt-ed for sliding movement relative to said frame 18, said trough being formed with laterally projecting flanges 22 near the tops of its longer sides adapted for sliding support on the slideways 19, 20. The drinking trough or pan 21 is elevated or depressed by rocking movement of the frame 14:, as will hereinafter more fully appear.

A supply pipe 23 leads from the major compartment or cattle drinking trough through and spaced somewhat above the bottom of the partition 13, being sealed by means of lock nuts 24, 25 (Fig. 1). The supply pipe 23 terminates ina substantially cylindrical, open topped valve chamber 26 located within the minor compartment and arranged at an elevation preferably a trifle above the uppermost position of the drinking pan 21, said supply pipe opening to the lower portion of said valve chamber. The valve chamber 26 is formed with a shoulder 27' comprising a valve seat, above the terminal end of the supply pipe 23, and a cylindrical valve 28 is fitted to the chamber and adapted for vertical movement therein and also. adaptedto rest on said seat at times. The valve chamber 26 is formed with a late-rally-extending spout 29 leading from a poi-ntfspaced above the valve seat 27 and d1scharging into the space occupied by the drinl'ringpan 21 being therefore adapted to supply water tosaid pan when it is in place and the valve is in open position.

A bracket 30- is secured to theouter face of the upper portion of the partition 13 and a stud or pivot bolt 31 projects from said bracket and forms the fulcrum for a lever 32 arranged parallel with and spaced some- What from said partition. The shorter arm of the lever 32 terminates substantially above the valve chamber 26, and a valve stem; is pivotally secured to said short arm of the lever, is vertically arranged, and

enters said chamber and is secured at its opposite end to the valve 28, in any suitable manner. The longer arm of the lever 32 terminates near the side wall 10 and substantially over that end portion of the rocking frame 17 opposite to the trough supporting frame 18 and pan 21, and a link 34 is pivotally secured at one end to the long arm of the lever, is vertically arranged, and is pivotally secured at its lower end to a bracket 35 rigidly mounted on the end of the rocking frame 17. In this manner operative connection is provided between the rocking frame 17, and the valve 28, so that Whenthe frame is oscillated in such manner as to raise the pan 21, the valve 28 is moved upwardly in the chamber 26, past the outlet through the spout 29, and permits a flow of Water from the pipe 23 through said valve chamber and spout; and when the frame is oscillated in the opposite direction so as to lower the pan 21, the valve 28 is lowered and firmly pressed against the seat 27 to stop the flow of water. The parts are so arranged and balanced that when the pan 21 is substantially filled the weight of the water causes an oscillation" of the frame 17 to lower the pan and close the valve, thus automatically stopping the flow of water when the pan is filled. It is the tendency also, when the supply of water in the pan 21 has been reduced beyond a certain point, for the opposite end of the frame 17, and members connected therewith, to overbalance the weight of the pan and its contents and raise said pan, thereby opening the valve and permit-ting water to flow and replenish the supply.

It is desirable to provide governing means to prevent too frequent oscillation of the rocking frame and consequent operation of the valve, as it is not necessary or desirable that the supply of water in the pan be replenished as often as; a smallpportion is removed therefrom. For this purpose I have provided a channeled track 36 suspended from and rigidly connected to the longer arm of the lever 32,. in which track a shifting weight, such as a roller 37, is mounted, one end of said track terminating near the pivot or fulcrum 31 of the lever and the other end terminating near the end of the long arm of the lever. It is-the function of the shifting Weight or governor 37 to travel from end to end of the track Stand-toward or away from the fulcrum 31, and axisof oscillation of the 0 frame 17, as the lever 32 is oscillated, thus increasing or decreasing the advantage of the longer arm of said lever; and a quantity of water of greater Weight than said roller will need to be added to or taken from the 10 pan before the devices will oscillate to operate the valve Thus the automatic valveoperatin devices are governed, steadiedand centre led.

A partition 38 preferably is mounted 1' lengthwise of and substantially on the me dian line of the minor compartment and separates the trough or pan 21 from that portion of the compartment containing the greater portion of the lever and governing 1 devices; it being understood that suitable openings (not shown) may: be provided through which the lever 32 and rocking frame 17 may extend and operate. If desired a heating device, such as a lamp, may 120 be mounted in that portion of the minor compartment opposit to the drinking pan 21 at times. A vertically slidable door 39 maybe provided to normallyclose the open end of the portion of the minor compart- 125 ment opposite to the drinking pan 21, and to provide access to the interior of such compartment at times, said door sliding vertically between spaced straps or bars 40 mounted across the top of the open end of the tank 130 structure. A hand hold 41 is shown in the door 39 to facilitate starting its vertical movement manually. The end portion of the tank structure adjacent the drinking pan 21 is preferably substantially open and permits insertion of the heads of animals such as hogs or sheep to drink from said pan; and also permits removal and replacement of said pan by endwise sliding movement. A removable cover 42 preferably is provided for the top of the minor compartment.

In Fig. 3 I have shown in detail the preferred construction by which I unite the side wall and bottom of the tank structure, to facilitate sealing said members to water tight condition and for general strengthening of the structure. As shown the bottom 11 is formed with a downwardly projecting marginal flange 43 contacting with the lower marginal portion of the side wall 10. The lower longitudinal angle frame member 12 has its vertical flange contacting with the outer face of the side wall 10, and its horizontal flange turned inwardly and extending across the margins of the said side wall and ofthe flange 43 of the bottom memher. A channel frame member 44 is mounted between the inwardly projecting flange of the angle bar 12 and the marginal portion of the bottom 11 and contacts with the inner face of the downturned flange 43 of said bottom, the open side of said channel member being turned inwardly. Connecting devices such as rivets 45 are mounted through the vertical flange of the angle bar, the marginal portion of the side wall, the flange of the bottom, and the body of the channel bar, and said members are drawn tightly together to sealing relation. Thus the sideand bottom members and the angle frame members are rigidly connected and reinforced, and additional support is provided for the bottom 11.

Water may be supplied to the major tank compartment or cattle drinking trough in any suitable manner.
